Our Response to Climate Change: HK2100

1: Revisiting Progress - At What Cost?

Introduction to Modern Progress:

• Equating progress with industrial growth, tech advancements, and urban expansion.
• Environmental costs often overlooked.
• Key question: “What environmental losses have we accepted for progress?”

Example 1: Deforestation in the Amazon:

• Accelerated deforestation post-2010s for agriculture.
• Impact: Loss of biodiversity, carbon storage, and indigenous habitats.
• Trade-off: Global food supply vs. ecological preservation.

Example 2: Urbanization of Green Spaces:

• Cities like Jakarta and Beijing expanding into green areas.
• Impact: Loss of natural spaces vital for air quality and biodiversity.
• Trade-off: Economic growth and housing vs. green space conservation.

Example 3: Intensive Energy Extraction:

• Shale gas boom, especially in the U.S., post-2010s.
• Impact: Groundwater contamination, seismic activity, methane emissions.
• Trade-off: Energy independence vs. environmental health.

2: Beyond CO2 - The Potent Greenhouse Gas Threat

The Methane Concern:

• Methane’s Potency: Methane (CH4) is over 25 times more potent than CO2 in trapping heat in the atmosphere over a 100-year period.
• Permafrost Thaw: Recent observations reveal accelerating permafrost thaw in the Arctic, unlocking vast methane reserves.
• Impact: Methane release from permafrost could significantly amplify global warming, contributing to a feedback loop.

Other Potent Gases:

• Nitrous Oxide (N2O): Emissions from agricultural activities, particularly fertilizer use, have been rising, with N2O being about 300 times more potent than CO2.
• Industrial Gases: Hydrofluorocarbons (HFCs), used in air conditioning and refrigeration, have thousands of times the global warming potential of CO2.

2.1: Beyond CO2 - The Potent Greenhouse Gas Threat (Cont’d)

IPCC Models and Tipping Points:

• Inclusion in Models: The IPCC has recently integrated permafrost melt and methane release into their climate models, highlighting the urgency of the issue.
• Tipping Point Concerns: There’s growing scientific consensus that we might be nearing or have crossed climate “tipping points,” leading to irreversible changes.

Examples and Analogies:

• Siberian Craters: The discovery of massive craters in Siberia, believed to be caused by methane explosions from thawing permafrost, serves as a vivid illustration of the methane threat.
• The Ice-Albedo Feedback: As Arctic ice melts, it reveals darker water that absorbs more heat, further accelerating ice melt and methane release from permafrost - a dangerous feedback loop.

Reflection:

• The rising threat of potent greenhouse gases challenges us to look beyond CO2 in our climate change mitigation strategies.
• Understanding and addressing these less-discussed but highly impactful gases is crucial in our broader fight against global warming.

3: Geoengineering - A Symptomatic Treatment?

The Shift to Geoengineering:

• Large-scale interventions in Earth’s systems
• Focus shifts from emission causes to climate symptoms management

Key Approaches:

• Carbon Capture and Storage (CCS):
  • Removes CO2 from the atmosphere
  • Stores it underground
• Solar Radiation Management (SRM):
  • Reflects sunlight away
  • Aims to reduce global warming

Ethical and Practical Concerns:

• Unintended Consequences:
  • Risk of unforeseen side effects
  • Potential to worsen climate issues
• Moral Hazard:
  • Might reduce urgency for emission cuts
  • Reliance on technological fixes

4: Questioning “Progress” and “Modernity”

The Untouchable Paradigms:

• Associated with tech advancement
• Often overlook environmental cost

Need for Paradigm Shift:

• Sustainable Progress:
  • Incorporates sustainability
  • Balances ecological concerns
• Inclusive Modernity:
  • Embraces diverse views
  • Values indigenous knowledge

Example: Transition to Renewable Energy:

• Shift from fossil fuels to renewables
• Symbolizes sustainable progress

5: Academia’s Pioneering Role

Fostering Diversity and Experimentation:

• Universities as idea incubators
• Promote cross-disciplinary research

Critical Thinking and Innovation:

• Challenges established norms
• Proposes innovative solutions

5.1: Silent Spring, or Power of Narrative

Rachel Carson, Chemist | Writer | Activist

5.2 Understanding System Thinking in Environmental Context

What is Systems Thinking?

• Holistic Perspective: Complex systems as interconnected wholes
• Feedback Loops: Recognizing how different elements within a system influence one another, non-linear

Interconnectivity in Nature

• Interaction of ecosystem
• Climate phenomena as result of interactions wtihin and between atmosphere, hydrosphere, geosphere and biosphere

Understanding System Thinking

• Empowers you to see the bigger picture and recognize the ripple effects of actions
• Encourages innovative and holistic solutions to environmental challenges through interconnectedness

5.3.1 ReIntroduction of the Wolves

5.4 Interconnectedness of species

6: Urgent Climate Issues We Cannot Ignore

Rising Sea Levels:

• Coastal erosion and flooding
• Threatens communities and infrastructure

Biodiversity Loss:

• Ecosystem collapse and species extinction
• Undermines Earth’s life support systems

Water Scarcity:

• Exacerbated by climate change
• Threatens food security and stability

7: Rethinking Cooperation for a Sustainable Future

Beyond Competition:

• Views Earth’s resources as shared

Innovative Governance:

• Develops flexible, inclusive agreements
• Empowers local action with global support

8: The Permafrost Time Bomb

Understanding Permafrost:

• Frozen ground in polar regions: 24% of Northern Hemisphere land surface
• Contains massive carbon reserves: 1700 Gigatons of carbon, 2x atmospheric carbon

The Thawing Threat:

• Warming temperatures causing thaw, twice as fast as global average
• Releases stored methane (25x) and CO2
• Permafrost to decrease by 30-70% by end of 21st century.
